Single engagement permanently secured keyless lock

ABSTRACT

A shackle has at least one lower end portion received downwardly in a body opening permanently engaged within the body by a split ring within the body expanding and then contracting into an annular groove of the shackle. The split ring is located within the body by a downwardly closed sleeve press fit upwardly into the body opening from a lower end thereof thereby preventing access to the split ring. An annular shoulder on the shackle locates the shackle within the body for such engagement. The shackle may be U-shaped for reception in two body openings or singular ended for one body opening.

BACKGROUND OF THE INVENTION:

This invention relates to a single engagement, permanently secured keyless lock which may be of the type having somewhat the outside appearance of a conventional padlock including a body and an inverted U- shaped shackle engageable with the body or may be of the type having a single end secured generally linear shackle engageable with the body, but in either case when once secured, is permanently secured and can only be removed by a complete destruction of the lock. More particularly to the principals of the present invention, the single engagement, permanently secured, keyless lock of the present invention may include one or more of various unique features such as a specific locating means for shackle engagement with the body ensuring complete and permanent engagement while increasing the security of such engagement, and means within the lock body which is positively operable to ensure automatic permanent engagement, yet of a simplified form and one which aids in guarding against outside tampering with the permanent engagement without complete destruction of the lock body. Furthermore, with the improved form of single engagement, permanently secured, keyless lock of the present invention, the same may be produced in an economically manufactured form so as to be provided at a minimum of expense in both manufacturing labor and material.

In the past, it has been common practice to provide simple seals of various types for use in sealing rail cars, long distance trucks and even smaller shipping containers shipped through common carriers, particularly where the shipment contains goods which may be of relatively small size, yet of relatively large unit value. One of the more common types of such seals has included a metal tape with a single, permanently engageable seal thereon which, when the shipping container is closed, may be quickly permanently applied and will be sufficient to show that the shipping container has been entered if the seal should be broken. These relatively insecure and easily broken types of seals had always been sufficient to deter the simple forms of pilfering.

With the recent trend of events, however, there has been a much greater incidence of attempted surreptitious entry into shipments of these types and the older, simpler forms of seals are no longer adequate. For instance, with the simple, metal tape forms of seals, not only can entry be gained with little delay, but it is possible to reassemble the seal so that at least the appearance thereof is sufficient to mask such entry. Thus, the entry of the shipment is not detected until a much later time, usually at the time the shipment reaches its final destination and is ready for unloading by authorized personnel.

In view thereof, there has developed a want and immediate need for a new, more secure form of seal which is not only of a more secure type but one which positively cannot be broken without virtually a complete destruction thereof. Not only must the seal give an appearance of greater security for deterring attempted shipment entries, but it must be of a type which requires the use of relatively large tools for the breaking of the seal which may be relatively easily observed by authorized personnel guarding the shipments. Still further, the seals must include these various advantages while still being of a relatively simple form which may be provided for a relatively low cost.

OBJECTS AND SUMMARY OF THE INVENTION:

It is, therefore, an object of this invention to provide a single engagement, permanently secured keyless lock which, when once permanently engaged, cannot be removed without virtually a complete destruction thereof. According to the principals of the present invention, the lock may be one of several somewhat conventionally appearing forms including the usual lock body and inverted U-shaped shackle, or a lock body and a single end inserted shackle with an enlargement spaced from the body. In either case, however, due to particularly formed engagement means within the lock body, once the shackle is brought intoproper engagement with the body, it is impossible to exteriorly release such engagement and the only possible manner of releasing the lock is to either exteriorly sever the shackle from the lock body or completely destroy the lock body.

It is a further object of this invention to provide a single engagement, permanently secured keyless lock of the foregoing general type which may include unique locating means on the shackle thereof which ensures proper location of the shackle during insertion thereof into the lock body for positive engagement therebetween. The shackle may include a specifically formed and located shoulder or shoulders thereon which engage a top surface of the lock body when the shackle is inserted therein and into the permanent engagement therewith. In this manner, not only is a relatively foolproof guide for proper permanent engagement between the shackle and lock body provided, but such guide aids in the overall security of the lock after such engagement by limiting possible movement between the shackle and lock body.

It is also an object of this invention to provide a single engagement, permanently secured keyless lock which gives the appearance of one of several forms of eliminate the possibility of inserting instruments in an attempt to release such permanent engagement. The result is, as hereinbefore stated, the necessity of completely destroying the lock construction in order to remove the lock.

It is still an additional object of this invention to provide a single engagement, permanently secured, keyless lock which satisfies all of the foregoing objects in a relatively simple and efficient manner so as to be capable of manufacture at a relatively economical cost. The lock of the present invention may thereby be used to replace the prior simple seal with only moderate cost increases. This is true despite the fact that the lock of the present invention is of greatly increased security and virtually tamper-proof without the complete destruction thereof.

Other objects and advantages of the invention will be apparent from the following specification and the accompanying drawings which are for the purpose of illustration only.

DESCRIPTION OF THE BEST EMBODIMENTS CONTEMPLATED:

Referring to the drawings, a first embodiment of the single engagement, permanently secured, keyless lock of the present invention is shown in FIGS. 1, 2 and 3, and includes a body generally indicated at 10 and an inverted U-shaped shackle generally indicated at 12, both of which, particularly in the engaged position, have somewhat the outside appearance of a conventional padlock.

Furthermore, the body 10 and the shackle 12 may be formed of any conventional material such as steel, aluminum and many of the modern plastics, all dependent on the strength and security required for the finished product, which of course, would be determined by the ultimate intended use. Also the particular material used would, in turn, determine the means of fabrication, all well known to those skilled in the art. 7

More particularly to the unique configuration of the 7 body 10 for purposes of the present invention, the body 10 is formed with spaced, substantially identical openings generally indicated at 14, preferably completely therethrough between upper surfaces 16 and lower surfaces 18 thereof. The openings 14 are each formed with upper reduced portions 20 extending uniformly cylindrical from the body upper surfaces 16 to intermediate the vertical length of the opening 14 and lower enlarged portions 22 extending uniformly cylindrical from the termini of the upper reduced portions downwardly to the body lower surfaces 18. Thus, the body openings 14 are formed with lower enlarged pockets which communicate upwardly through the upper reduced portions 20 through the body upper surfaces 16.

The once-engageable gripping member in the form of a resilient split lock ring 24 is positioned in each of the lower enlarged portions 22 of the body openings 14 generally at the vertical location of the upper extremities of the lower enlarged portions 22. The lock rings 24 in their normal contracted conditions have outer diameters larger than the upper reduced portions 20 of the body openings 14 and inner diameters spaced less than said upper reduced portions. Furthermore, the lock rings 24 are retained in their general vertical locations by underlying sleeves 26 press fit upwardly into the lower enlarged portions 22 of the body openings 14 with internal diameters approximately equal to the upper reduced portions 20 of the body openings and being closed at their lower ends coterminus with the body lower surfaces 18 so as to form closed continuations of said body lower surfaces.

The inverted U-shaped shackle 12 includes spaced leg portions 28 upwardly joined by a preferably arcuate connecting portion 30, the leg portions likewise being substantially identical asthe body openings 14 and their lock ring and sleeve assemblies 24 and 26 therein. Lower parts 32 of each of the leg portions 28 are of reduced diameters terminating uniformly upwardly in outwardly projecting parts or annular shoulders 34, the shackle 12 preferably being of the enlarged shoulder diameter from said shoulder, the remaining upward vertical extent of the leg portions 28 and continuously along the connection portion 30. Important to certain of the principles of the present invention, the maximum diameters of the leg portion lower parts 32 which extend uniformly the majority of the lower part lengths downwardly from the shoulders 34 are slightly less than the uniform diameters of the upper reduced portions 20 in the body openings 14,- and the enlarged diameters of the shoulders 34, as well as the upward remainder of the leg portions 28 and the connecting portion 30 are spaced larger than the upper reduced portions 20 of the body openings 14.

Spaced upwardly from the lower ends of the leg portion lower parts 32 and intermediate such lower parts are formed annular grooves 36, with said lower parts terminating downwardly in inverted frusto-conical ends 38 preferably beginning spaced below the annular grooves 36. It will be noted that the annular grooves 36 are located 'on each of the leg portion lower parts 32 spaced below or downwardly from the leg portion shoulders 34 a distance slightly greater than the vertical extent of each of the upper reduced portions 20 of the body openings 14. It will also be noted that whereas the diameter of each of the leg portion lower parts 32 of the shackle 12 both upwardly and downwardly adjacent the annular grooves 36 are of greater diameters than the normal inner diameters of the lock rings 24,

portions of the lower part frusto-conical ends of the shackle leg portions 28 are less than said retracted lock ring inner diameters particularly in the lower regions of such frusto-conical ends.

Thus, with the body and shackle 12 of this first embodiment of the single engagement, permanently secured, keyless lock of the present invention separated, but constructed and, where necessary, assembled in the manner hereinbefore described,-the shackle may be used as the prior seals or as the conventional padlocks for engaging the closed conventional hasp of a railcar, truck or other form of shipping container, or, as a matter of fact, any structure or article to be retained sealingly closed, and the shackle leg portions 28 inserted downwardly into the openings 14 of the body 10 in the manner shown in FIG. 2. As the lower frusto-conical ends 38 of the shackle leg portions 28 enter and pass downwardly through the body lock rings 24, the lock rings will ultimately be sprung resiliently outwardly in the manner shown in FIG. 2 until the shackle leg portion shoulders 34 engage the body upper surfaces 16 and simultaneously therewith the body lock rings 24 engage and retract into the annular grooves 36 of the shackle leg portions in the manner shown in FIG. 3. During such insertion of the shackle 12 into the body openings 14, the parts of the shackle leg portions 28 below the shackle annular grooves 36 will enter the body sleeves 26 as shown.

The result is that, due to the retraction of the body lock rings 24 into the annular grooves 16 of the shackle leg portions 28 and the fact that these lock rings are vertically trapped between the upper ends of the body opening lower enlarged portions 22 and the body sleeves 26, the shackle 12 is permanently secured or engaged with the body 10 and can never be removed therefrom without either a complete destruction of the body or a severing of the shackle at a location above the body. As described, this positive single engagement and permanent securement between the body 10 and the shackle 12 is perfectly located and ensured by the downward engagement of the shackle leg portion shoulders 34 with the body upper surfaces 16, not only serves to provide such exact location, but also limits movement between the body and shackle after such engagement for deterring attempts to forcibly separate the same, adding to the strength and security thereof. Also, the body sleeves 26 not only properly position the lock rings 24 within the opening lower enlarged portions 22, but the lower closed ends and the termination thereof at the body lower surfaces 18 of such sleeves greatly deters attempted manipulation from below of the lock rings 24 in an attempt to disengage the same from the shackle annular grooves 36, again adding to the security and strength of the engaged body and shackle 10 and 12.

A second embodiment ofthe single engagement, permanently secured, keyless lock of the present invention is shown in FIGS. 4, 5 and 6, and different from the U- shaped shackle form of the first embodiment is of a linear shackle form. As shown, this linear shackle second embodiment form includes a cylindrical body generally indicated at 40 having only a single opening generally indicated at 42 therethrough between upper surfaces 44 and lower surfaces 46 thereof. The opening 42, however, is virtually the same as each of the openings of the first embodiment having an upper reduced portion 48 and a lower enlarged portion 50 with a lock ring 52 retained in an upper part of the lower enlarged portion by a sleeve 54 inserted upwardly press fit into the lower enlarged portion downwardly closing the opening.

A linear-type shackle generally indicated at 56 has a single, linear leg portion 58 which terminates upwardly, preferably integral with an enlarged, transverse end portion 60 forming the upper termination of the shackle. Otherwise, the shackle leg portion 58 in its downward extension is virtually the same as a single of the leg portions of the first embodiment shackle having a reduced diameter lower part 62 terminating upwardly in an outwardly projecting part or annular shoulder 64, an annular groove 66 intermediate the lower part and an inverted frusto-conical end 68 below the groove and downwardly terminating the lower part.

Thus, in the use of this second embodiment linear form, with the body 40 and the shackle 56 separated, the leg portion 58 of the shackle may be inserted into many of the same things as could be locked with the first embodiment U-shaped form depending on the particular structures thereof, such as the hasps of railcars, trucks or other forms of shipping containers. In this case, however, the shackle 56 has the leg portion 58 thereof inserted until the shackle-enlarged end portion 60 engages the particular structure being locked or sealed preventing further insertion of the shackle leg portion, and then the lower part 62 of the shackle leg portion 58 is inserted into the body opening 42 for permanent engagement therein retained by the lock ring 52 received in the shackle groove 66 as before. The shoulder 64 of the shackle leg portion 58, as before, locates the shackle 56 within the body 40 and the body sleeve 54 prevents any attempt at manipulation or tampering with the final permanently secured engagement.

According to the principles of the present invention therefore, various forms of a single engagement permanently secured, keyless lock are provided which, when once permanently engaged, cannot be removed without virtually a complete destruction thereof, thereby positively signalling any tampering with such locks and any removal of such locks from that with which they are sealingly engaged. Furthermore, the constructions of the present invention are of a unique and relatively foolproof form, not heretofore provided by the prior seal or permanently engaged lock constructions. Despite all of these clear advantages, the constructions of the present invention are of forms which may be relatively economically produced so as to be provided with the increased security advantages thereof at a cost only modestly increased over the prior very simple, and far less secure seal constructions.
